Harmonic Prodigy

Doubling triggered abilities has historically lived in red-white, so packing the effect into a mono-red two-drop is the design wrinkle here. The doubler works on any triggered ability from a Shaman or Wizard you control, which quietly turns a whole tribe of interactive utility creatures into engines: the ping doubles, the draw doubles, the drain doubles. What keeps it from spiraling is the tribal restriction and the body's own limits. Notably, it doesn't double its own prowess, and not for any subtle stack reason: prowess is a triggered ability of this creature, but the text only doubles triggers from "another" Wizard, so the source is excluded by name. It also touches nothing off-type. The 1/3 frame is telling: this is a support piece built to survive the incidental damage that flies around wizard decks, not a threat that closes games. The doubling functions like Panharmonicon reframed for tribal triggered abilities rather than enter-the-battlefield effects, and it stacks with a second copy, so two of these on the board triple the relevant triggers. The card is a payoff waiting for a critical mass of Shamans and Wizards with abilities worth firing twice, the kind of build-around that rewards a deck's density rather than a single flashy line.
